MEANS FOR REGULATING l'HE TEMPERATURE OF BEER, SLC.

SPECIFICATION forming part of Letters Patent No.308,666, dated December 2, 1884.

l Application filed August 8, 19.84.` (No model.)

To @ZZ whom it may concern,-

Be it known that we, JosIAH S. HALEY and RAYMOND F. RoswALD, citizens of the United States, and residents of the city and county of New York and State of New York, have l invented a new and useful Improvement in Means of Regulating theTemperature of Beer and other Fluids in Oasks and other Vessels,

of which the following is a specification, reference being had to the accompanying drawings.

Hcretofore it has been the practice of brewers vand other persons whose business `it was to handle and store beer, ale, porter, and like fluids to keep such iiuids in casks, in cellars, and other chambers, in which, when necessary, were packed large quantities of ice to,

actas a refrigerant to the entire chamber. Necessarily this entailed great labor and ex- 2o pense in preparing suitable chambers, storing ice, and keeping up a supply of ice in the chambers where the casks of iiuid were stowed. Sometimes, to accomplish the same purpose, a blast of cold air was forced into the chamber where the liquid was stored to act as a refrigerant and cool all the atmosphere of the chamber. This was only accomplished at a great expense of power, which was necessarily very costly, and in many cases it was found, after great expense and trouble, that the apparatus was inadequate to accomplish the purpose for which it was constructed.`

The object of my invention is to provide such an apparatus as will do away with a great deal of this labor and expense of cooling liquids stored in' casks and other large vessels, in a much better and a much cheaper way than has heretofore been in use.

The invention consists in the combination, 4o with a vessel containing the liquid which is to be cooled and kept at a uniform temperature below the surrounding atmosphere, of a cooling apparatus and train of circulatingpipes which are arranged so that they are partly within said vessel and partly within the cooling apparatus, a circulating device for producing a circulation of refrigerating-liquid through said pipes, a valve within said pipes, and an expansion-rod within said vessel connected with said valve, to control the flow of refrigerating-liquid through said valve.

Figure l is a vertical sectional view of a Cask and apparatus illustrating my invention. Fig. 2 is a horizontal section of the same cask and its immediate appurtenances.

Similar letters of reference denote corresponding parts in all the figures.

i A is a vessel in which the beer or other liquid to be cooled is stored. It may be of any convenient construction, and may be made of any suitable material. The example given illustrates au ordinary wooden beer-cask.

B is the refrigerating device, which may be, as illustrated in the drawings, a box in which the cold is directly derived from ice in contact with the circulating-pipes; or this device may be in any other cheap and proper form, in which cold may be produced in any other economic and convenient way, either by ice, freezing-mixtures, or mechanical apparatus. Y

O O is the circulating-pipe, which, bending in serpentine form, passes through a part of the iuid in the cask, through the refrigerator B, and, bending at h and g, extends to the circulating-pump E, to which it is connected in the usual way for producing circulation.

D is the expansion-rod, which being fastened in one head of the cask, passes through the iiuid and through a stuffing-box, n, inthe other head, and projects outside of the vessel. rlhe inlet end C of the circulating-pipe is provided near the cask with a double bulb, (designated by bf.) In one lobe of this double bulb, against e', the throat of the inlet-pipe C, is iitted the valve b. This valve is attached to the longer arm of a lever, r, which is pivoted at b in the narrow space between the two lobes ofthe douy ble bulb b f, and attached by its shorter arm to the projecting end of the expansion-rod D. The circulating-pipes are provided with suitable stop-cocks at a and c. f

At 0 o is placed a thermometer, which may be of any suitable forni. ln the example given the tube of the thermometer is bent, so that while the bulb o is inside of the cask the said tube, passing through a hole, m, in the head of the cask, displays its gradations on the outside of the cask, as illustrated in Fig. 1. rlhis hole m in the head of the cask may be packed with india-rubber or any other suitable material to prevent leakage. In the example given the circulating device is an ordinary steam forcepump. It may, however, be a rotary pump, centrifugal wheel, or of any other convenient forni suitable to produce a suiiicient current in the circulating-pipe C C.

To use our invention the cask is lled with beer or other liquid to be cooled, the refrigerator B packed with ice or otherwise prepared to make cold, and the circulatingpipe C C filled with brine or any other fluid which may be reduced to a low temperature without congelatiou. The circulating device E is then set in motion to produce acurrent through the circulating-pipe C C. It will then be found that the iuid in the circulating-pipe C C,in passing through the refiigerator,\vill be very much reduced in temperature, and passing from thence through the part of the pipe in the cask, will reduce the temperature of the fluid in the cask much below that of the surrounding at1nos phere, and when the temperature is as low as desired will retain approximately that condition as long as the current in the pipes continues and the cooling process is kept up in the refrigerator. If the temperature of the uid in the cask falls, the expansion-rod D,by contracting, will cause the valve-lever t0 which it is attached in the double bulb bf to turn on its pivot and partly close the valve over the throat z' of the inlet-pipe C, and by obstruct ing the low of the fluid in the circulatingpipe cause a weaker 'liow in the part in the cask. If the fluid in the Cask should grow warmer, the expansiolrrod, expanding, will open thc valve and allow a more copious iiow of thecool brine through the circulating-pipe. Thus the expansion-rod D acts as a governor to control the iiow of the fluid in the circulating-pipe, and thereby to regulate the temperature of the iluid in the cask.

Vhat We claim as our invention, and desire to secure by Letters Patent, is-

The combination, with a vessel for containing liquid which is to be kept at a nearly uniform temperature below that of the surrounding atmosphere, of a cooling apparatus, a train of circulating-pipes arranged partly within said vessel and partly Within said cooling apparatus, a circulating device for producing the circulation of a reirigeratiiig-liquid through said pipes, a valve in said pipes, and an expansion-rod in said vessel connected with said valve, substantially as and for the purpose herein set forth.
